Ferrea's Valve components for FRS/BRZ
 

See this video... Interesting! I think they are first to even announce anything like it for our cars.

300HP NA...oh dear god

This is awesome. Really liking how quickly the market has responded to the platform.

I want! :drool:

WOW I see 10K RPM in this engines future.

I cant wait to see what a fully built street motor can put out. And yeah no doubt we will see some ridiculous redline from peoples builds.

This engine in mostly stock form with lots of head work, cams, and mild boltons, I can see making at least 250 and even 300whp NA with far more crazy work.

I come from Honda's where my personal 1.8 makes 240-250whp with a 100% OEM parts block. People where keep saying I am crazy, however K20 engines can make 250-275 with far less work than I have on my B18.

BONER.

300HP N/A? Running E85 or race fuel, I guarantee it.

I wonder how much the race performance package and street performance package he mentioned in the video will cost and how they would change the car in terms of daily drivability. I doubt it will just give you more power. I'm guessing there are trade-offs somewhere or negatives to have these in a daily driver type car. I'd be curious to know that they may be. Also be interesting if these would be cheaper than getting a turbo or supercharger for the same amount of horsepower.

Based on the fact that you're very likely pulling the engine...I'd imagine something like the basic AVO kit would be cheaper. Skilled Subaru mechanics can adjust valves with the engine in the car, but I'd imagine if you're replacing the entire valvetrain you'd want to pull it out, no? The trade-off with valves is usually low-rpm torque (and drive-ability) for high-rpm power.

i get the feeling that 300 na hp is more expensive and less reliable than 300 fi hp.

So complete race/performance heads are like $5,000 (thats how much cosworth heads are on ej25) and with custom intake manifolds are like $2,000. And you might need a race/performance short block to go with it. So i wonder how much complete package will cost. Btw cosworth ej20 heads are good up to 10,500 rpm

Btw complete cosworth engine is about $12,000

I think it might be pretty reliable (if the rods don't fatigue) but it'll be more finicky. With a significant increase oil pump might need to go, water pump will be spinning too fast, and the short rods will place a lot of stress on the cylinder walls.

The heads and the direct injection are designed together for low end, if this involves more modification than replacing some components (aka, changing the ports) the low rpm behavior could really suffer. If it's just lighter valves, stiffer springs, bigger cams, shouldn't be too big of a deal. The cam phasing has a pretty wide range to deal with fat cams (if you add like 60 degrees duration on the intake though the idle is probably going to suck no matter what magic Toyota says direct injection can do with EGR, but if it's more modest like 30 degrees maybe not).

Power peak at 9000rpm and E85 could hit 300hp.

would be a shitload of fun despite my expectations of the costs involved

Im pretty sure its gona cost way more to do the n/a high hp road, than to go with a simple bolt-on tc/sc kit...

He didn't just say 300 Hp NA !!!

Nothing is more fun that high revving, large NA Hp. You can't comparing it to boost.

if i can get 250+ whp N/A with a mild build, way worth it

good stuff, now you just need a solid cam option

Thread cleaned up. Please keep it on topic and stay away from the NA vs. FI arguments.

wrong! more revs mean less torque. crew that!

The market's been mum on this as far as I've seen. Of course you get a custom regrind, but an off the shelf variety of options would be cool.

Ive heard Tomei and Perrin are both coming out with cams, excited to see how they help this car. And how these cars will sound with them most of all.

250+ Hp NA on this car would be spectacular.

I hope Jun makes some cams. I love my Jun 3 cut cams.

Perrin has never made cams for a Subaru...Jun, Tomei, even HKS I could see. I'm hoping for something more along the lines of Kelford, GSC, maybe Cosworth.

HMMM. I don't like how he said they've done only two builds, yet he was saying "guys" plural are getting near 300 from normally aspirated. The wording of the question and subsequent answer leads me to believe the guy is basically bullshitting his numbers. I mean come on, aftermarket exhaust valves having no trouble at all with 11, 12 lbs of boost? I'm pretty sure the stock valves have been handling that already.

So what all is it going to take to get this thing to rev to 9000 reliably?

Nice to see another Honda guy here. While i don't expect any other car to come close to Honda as far as HP/liter, i've already fallen in love with this platform for its handling, and even though its got less whp than my RSX-S had, it definitely feels faster sooner than my NA K series.

My boosted Honda is whole different story... 500HP in a ~2000lb chassis is just stupid fast. terrifying really.

I cant wait for my warranty to be up on my BRZ.

I know Brian Crower is working on a set of cams currently. And can verify that as of SEMA time, Cosworth's goals were to get some intake and exhaust parts together first for the FA20 platform and cams were not even discussed.

We saw this Ferrea setup in person at SEMA and it looks amazing, we will have a set on the way for our motor build on our shop FR-S.

Bump. Any updates or news on these or any other internals being worked on for NA apps?

the 11 12 lbs of boost they were talking about the new gm crate engine, no the FA20.

the trade off to 300na hp will definitely be low end torque that will suffer quite a bit.

as far as how to get 300 hp from the engine, he said they have a new head, it ain't just valves and springs. pretty sure some custom cam was involved to add 100hp but it would still be pretty nice to hear.

and for running 9k rpm you'd have to get a bigger water pulley to slow it down for sure cause i read someone here saying over 7400rpm the water pump starts to cavitate.

Very good point. Cavitation is a killer.

Or you can clip off the tips of the impellers on the water pump. Common "trick" on production based race cars. Often times it's done for the purpose of cheating (reduce the drag from the water pump) but hey... just sayin'.

bump for updates....

As a track day guy and daily driven car, I just want the "valley"to be gone(maybe mild cams) and 230whp( car doesnt weight much). Normally mild cams dont kill bottom end and increase top end in a decent manner with gains in the mid range. Consider with the "valley" gone....this car REALLY has a nice pull to it. Hell most of us just want 200whp with simple bolt ons( not sure how realistic that is but.....).

Maybe a USA company will make some mild cams that arent a tall order to tune and reasonably affordable. Then again when I decided to take the high road and NOT do force induction, I knew then it would cost MORE to get decent power.

Oh and that 230whp I want is on pump(93). Maybe if it still made decent power at 7500 then good.

Thats all THIS suspension guy wants !

It's nice to know I'm not the only one! :D

2yrs later....
Whatever happens to this? Was there any valvetrain kit produced for the frs?
